Validations in Transformer fails but pipeline works?

Issue:

Validation provides the below error.

FILE_OPERATOR_ERROR_08 - Unable to access FileSystem: Status Code: 400, AWS Service: Amazon S3, AWS Request ID: 82E477F7EDA0BDF3, AWS Error Code: null, AWS Error Message: Bad Request

Even though, the pipeline runs successfully 

Versions affected:

3.13.X and previous versions. 

Solution:

If the pipeline is configured in (CDH/HDP YARN or Databricks Cluster), select a remote preview (fg1) in order to validate and preview the pipeline using the configured cluster.
